The above-mentioned concrete size of skew brick and specification can be determined according to actual conditions, as a kind of preferred embodiment, the concrete size of skew brick can be: a is 285 ~ 295mm, a1 be 256 ~ 260mm, b be 165 ~ 175mm, R1 be 1520 ~ 1530mm, R2 is 1350 ~ 1360mm, and c1 9 ~ 11mm larger than c.And particularly, in the present embodiment, skew brick has A1 ~ A8 eight kinds of specifications, corresponding thickness c is respectively 9 ~ 11mm, 19 ~ 21mm, 29 ~ 31mm, 39 ~ 41mm, 49 ~ 51mm, 59 ~ 61mm, 69 ~ 71mm, 79 ~ 81mm and 89 ~ 91mm.
On the other hand, the present invention also provides a kind of ladle wall laying method, and this building method adopts above-mentioned skew brick and a kind of brick laid on flat to build ladle wall by laying bricks or stones, and the detailed process of this building method is:
First, adopt chamotte levelling to the bag wall substrate of ladle;
Then, skew brick is adopted to build the section of starting by laying bricks or stones, be that the x (x >=1) that the skew brick of A1 ~ An is equidistantly separated by successively respectively from the substrate of bag wall builds the section of starting by laying bricks or stones in the same direction by specification, until form the layer of starting being less than or equal to a circle at the bottom of bag base, then adopt a kind of brick laid on flat respectively then last block skew brick of each section of starting continue to build brick laid on flat by laying bricks or stones, until build the top of ladle by laying bricks or stones, the cross section of wherein used brick laid on flat is fan-shaped, the external arc edge lengths of the cross section of this brick laid on flat is a ', Inner arc edge lengths is a1 ', and the side edge length of this brick laid on flat, equal all with used skew brick of external arc limit place radius of a circle and place, Inner arc limit radius of a circle, the thickness of this brick laid on flat is equal with the thickness c1 of last block skew brick of the section of starting,
Finally, fill up the space between the laying bricks of ladle wall, adopt castable integrated poured to ladle wall.
Particularly, the brick laid on flat adopted in the present embodiment is of a size of: a ' is 285 ~ 295mm, a1 ' is 256 ~ 260mm, and the thickness of this brick laid on flat is 89 ~ 91mm, represents this brick laid on flat herein with B.
Specifically describe the process adopting this building method of ladle wall of the present invention to build ladle wall by laying bricks or stones for present embodiment below in conjunction with Fig. 2 and Fig. 3.
In ladle wall laying method of the present invention, x can according to ladle and the suitable value of the size Selection of laying bricks, such as, as shown in Figure 2, in the present embodiment, the value of x is 2, similar double-helical mode is adopted to build ladle wall by laying bricks or stones, namely start in the same direction respectively from two of ladle wall substrate relative point M and N and build ladle wall by laying bricks or stones, in Fig. 2, just whole ladle wall is along the vertical line expansion at some M place, more clearly to describe ladle wall laying method of the present invention.
In bag wall building process, first, adopt chamotte levelling to the bag wall substrate of ladle.
Then, employing skew brick is started, particularly, in the present embodiment, as shown in Figure 2, start along clockwise direction respectively from two of ladle wall substrate relative point M and N, the skew brick being A1 ~ A8 by specification is built by laying bricks or stones along ladle wall substrate clockwise successively from M and N edge respectively, because the thickness c of thickness c1 and the An of An-1 is equal, therefore the upper surface of skew brick A1 ~ A8 forms a slope, these eight pieces of bricks constitute the layer of starting that bag wall is built by laying bricks or stones, after having built A1 ~ A8 by laying bricks or stones, then brick laid on flat B is built on the limit of the thick c1 of A8 by laying bricks or stones, until built a circle by laying bricks or stones, namely when the brick of the relative both sides of bag wall substrate is all built by laying bricks or stones to P place in figure, now, continue to build brick laid on flat B by laying bricks or stones, as shown in Figures 2 and 3, due to along a direction the distance of building between last block brick brick laid on flat B of half-turn and first piece of brick skew brick A1 of built in opposite direction half-turn be less than the length of one piece of brick, therefore, then along a direction build half-turn last block brick brick laid on flat B brick laid on flat B of continuing to build by laying bricks or stones can ride on first piece of brick skew brick A1 of built in opposite direction half-turn, formed " bridging ", as shown in Figure 3, a space D can be formed in the bottom of this " bridging ", then, continue along slope to build brick laid on flat B by laying bricks or stones, until build the top of ladle by laying bricks or stones.Be divided in two half-turns double helix masonry way that layering is built by laying bricks or stones along slope respectively by ladle wall this, during the two pieces of brick laid on flat B building each circle by laying bricks or stones encloses with upper one respectively, often last block brick of half-turn connects.
Finally, adopt brick slag fill up the space D of described " bridgings " bottom and ladle wall lay bricks between other space, then employing castable is integrated poured to ladle wall.
Wherein, above-mentioned skew brick, brick laid on flat and chamotte can adopt and well known to a person skilled in the art that any refractory material is made, and such as, the skew brick adopted in present embodiment and brick laid on flat are aluminium-magnesia carbon brick, and chamotte is magnesium chamotte.
Ladle wall laying method of the present invention is applied in Pangang Group Panzhihua Steel Vanadium Co., Ltd., such as, adopt building method of the present invention to climbing steel steel mill G24 ladle (ladle lower internal diameter 3m, upper internal diameter 3.45m, high 3.75m in ladle) build by laying bricks or stones, A1 ~ A8 is adopted relative two to start and build by laying bricks or stones from ladle wall substrate, build bag nogging 40 layers altogether by laying bricks or stones, within 4 hours consuming time, namely complete bag wall to build by laying bricks or stones, this ladle reaches 118 times service life, and for example, adopt building method of the present invention to climbing steel steel mill G06 ladle (ladle lower internal diameter 2.95m, upper internal diameter 3.43m, high 3.72m in ladle) build by laying bricks or stones, A1 ~ A8 is adopted relative two to start and build by laying bricks or stones from ladle wall substrate, build bag nogging 40 layers altogether by laying bricks or stones, within 3.8 hours consuming time, namely complete bag wall to build by laying bricks or stones, this ladle reaches 124 times service life.
When using according to ladle wall laying method of the present invention, due in ladle building process, the space (i.e. space D) between refractory brick is very little, therefore without the need to " conjunction door ", thus make operation simpler, and save the time of building by laying bricks or stones, accelerate bag wall and build speed by laying bricks or stones.
Below the preferred embodiment of the present invention is described in detail by reference to the accompanying drawings; but; the present invention is not limited to the detail in above-mentioned embodiment; within the scope of technical conceive of the present invention; can carry out multiple simple variant to technical scheme of the present invention, these simple variant all belong to protection scope of the present invention.In addition, each the concrete technical characteristic described in above-mentioned detailed description of the invention, in reconcilable situation, can be combined by any suitable mode, as long as it is without prejudice to thought of the present invention, it should be considered as content disclosed in this invention equally.
